Properties
| Field | Type | Label | Description | |
|---|---|---|---|---|
identifier | string | An identifier for the segment in the format of domain:system:type:id, for example, "here:cm:segment:3455277". This property is unique in a catalog. | ||
start_node_ref | Reference | The start node for the segment. Given that the start node defines a segment's partition affinity, the start node must be in the current partition. | ||
end_node_ref | Reference | The end node for the segment. The end node may be in different partition. If the end node is the same as the start node then the segment is a loop. If the segment is a loop and no other segments reference its node, then it is an isolated loop. If the segment is a loop and at least one other segment references its node, then the segment is a cul-de-sac loop. | ||
geometry | LineString | Line string geometry for the segment, running from start to end node. | ||
length | double | Length of the segment in meters. | ||
